PS, coated with poly-lysine. Poly-D-Lysine (PDL) and Poly-L-Lysine (PLL) are synthetic molecules that are used to improve the adhesion of different cell types to polystyrene surfaces. The cultivation efficiency of individual cell lines can be improved, especially when serum-free or serum-reduced medium is used, or when experiments such as transfections are performed. As the PDL is synthetic it is free of the impurities carried by other proteins.

• Improved cell adhesion, proliferation and growth of transfected cell lines (eg. HEK-293, PC12, L929, certain 3T3 cell lines), neuronal cell lines, as well as primary neurons and glia cells
• Suitable for serum-free or serum-reduced cell cultivation
• Cell differentiation and neuron growth
• Quality control tested to demonstrate promotion of the adhesion of RCG cells (rat neurons from the cerebellum)

Molecular weight: PDL 75 to 150 kD; PLL 30 to 70 kD.

Shelf life: 24 months at room temperature
